TOOTH-BRUSH.

1,018,927. Specification of Application filed July 14,

To all whom it may concern I Be it known that-"I, JULES J. SARRAZIN, acitizen of the United, States, and a resident of New Orleans, in theparish of Orleans, State of Louisiana, have invented certain new anduseful Improvements in Tooth-Brushes, of which the following is aspecification.

This invention has for its object to provide a tooth brush which is soconstructed that it will more readily and thoroughly cleanse the teethand be more readily controlled by the user than the ordinary toothbrushes now on the market, and to this end it consists in a novelarrangement of bristle tufts and a construction to be. hereinafterdescribed and claimed.

In order that the invention may be better understood, reference is hadto the accompanying drawing, in which ,Figure 1 is a plan' view of thebrush; Fig. 2 is a side elevation of the brush head, and Figs. 3 and.4.- are longitudinal and transverse sections, respectively, of thebrush head. i

Referring specifically to the drawing, A

head, the latter being tapered in the direction of its forward end andjoined to the handle by an elongated neck a, which latter allows freemanipulation of the brush in all parts of the mouth, and around theteeth and the gum margins without hindrance by the muscles and tissuesof the mouth and cheeks of the user, and, consequently, with greatercomfort.

At the forward end of the brush head are several tufts of bristles whichare bunched or grouped closely together to form a prominent projectingpoint B. The bristles of this group are cut so that the contour thereofis given a transverse and longitudinal curve. The remaining tufts ofbristles b of the brush head extend in converging longi tudinal rowsfrom the rear end of the brush head to the point B, and they are alsoarranged in straight rows extending transversely of the brushhead. Thenumber of tufts in the transverse rows is not uniform, the forward rowshaving a less number than the rear rows. As shown in Fig. 1. of theLetters at n Patented Feb. 27, 1912.

1911. Serial No. 638,547.

each extend from the rear end to about the middle of the brush head, andbetween the latter and the point B are three rows of three tufts each.Of course, the number of tufts in the transverse rows may be varied,provided the forward rows contain a smaller number than the rear rows.

By the herein-described arrangement of tufts b it is possible to producea short the forward end thereof except at the point B. It is desirableto have the tufts spaced from eachother in order that they may getbetween the teeth. Without this reduction of numbers of tufts in theforward transverse rows, the tufts would betoo solidly massed at thisportion of the brush and they would therefore be prevented 'from passingfreely between the teeth.

The bristles b are cut or arranged so that acentral longitudinal groove0 ishad,which groove, however, does out the entire length of the brushhead, but stops short of the point B. As shown is in the first one ofthe transverse rows having the smaller number of tufts, thus which isnext rear end of'the brush head, from which it gradually decreases indepth and width up to the end 0'- v The herein-described groove 0 servesto guide the brush along the edge, of the bicuspids and molars of boththe upper and lower jaws, and thus holds the point B to .itsyproperworking position along the gum margins.

I claim A tooth brush having a short head which is tapered toward itsforward end, and bristle tufts on said head arranged to form an elevatedpoint at head, and said head also having, bristle tufts arranged inlongitudinal and transverse rows, the longitudinal rows converging inthe direction of the forward end of the head, and the number of tufts inthe transverse rows at the forward end of the brush being less than thatin the transverse drawing, four transverse rows of four tufts rows tothe rear thereof, and said tufts betapered brush without bunching thetufts at I leaving intact the other transverse row to the point B. Thedeepest and widest. portion -of the groove is at the not extendthrough-.

in Fig. 3, the groove terminates at C which 7 the forward end of the;

ing arranged to form a central, longitudinal aflixed my signature in thepresence f two groove which commences at the rear end of the head andterminates at'a point-spaced fromthe elevated point, andsajd groove de-5 creasing in depth and Width toward the forward end of 'the head. I y

In testimony whereof, I have hereunto witnesses;
